Prototype

int ispunct(int c);

int iswpunct(wint_t c);

int _ismbcpunct(unsigned int c);

Description

Tests for punctuation character.

ispunct is a macro that classifies ASCII-coded integer values by table lookup. The macro is affected by the current locale's LC_CTYPE category. For the default C locale, c is any printing character that is neither an alphanumeric nor a blank space (' ').

You can make this macro available as a function by undefining (#undef) it.

Return Value

ispunct returns nonzero if c is a punctuation character.

Example

#include <stdio.h>
#include <ctype.h>
int main(void)
{
  char c = 'C';
  if (ispunct(c))
    printf("%c is a punctuation character\n",c);
  else
    printf("%c is not a punctuation character\n",c);

  return 0;
}
